Positives:
The installation worked without bubbles at once, the feeling is as good as the original display and responsiveness of the display is not affected.
Neutral:
The glass has a thickness of 0.4 mm. Unfortunately, the smartphone no longer fits after mounting in the actual Xperia Z3 adapter of the original Sony charger so that the next larger adapter must be used. The smartphone now wobbles in the charging cradle and has a few times back and forth to be pushed until the charge is carried out. This circumstance should be taken into account buyer definitely, this will probably also be the case with glass films from other manufacturers, so it was assessed neutral from me.
Negatives:
The cutouts for the speaker and the LED lamp are very high, which does not look visually appealing.
Conclusion:
I probably would not buy me this glass sheet due to the thickness and the unsightly gaps again. I forgive but because I have no comparison to other window films for the Xperia Z3, nevertheless 4 stars for the simple introduction without bubbles, the feeling and the continued good responsiveness of the display. The film lived up to its purpose.
